The situation when the sticker on the refrigerator door is erased or the technical passport is lost is familiar to many owners of household appliances. At this point, the search for compatible spare parts, filters or instructions turns into a real quest. However, manufacturers leave hidden clues right in the name of the device, which can often be found on the internal label or in the warranty card.
Understanding the logic labels allows you not only to identify the device, but also to find out its year of manufacture, country of assembly and even the color of the case without visual inspection. This is critically important when ordering rare components, where an error in one letter can lead to incompatible parts. In this article we will analyze the encoding algorithms of the world's leading brands.
Where to look for identification data on the case
The first thing you need to do before trying to decrypt is to find the label itself. The standard location of the label depends on the design of the refrigerator and the manufacturer's policy. Most often, a sticker with serial number and model is located inside the refrigerator compartment.
Usually it can be found on the left or right side wall, less often - on the inside of the door or on the ceiling of the chamber. In some models, the information is duplicated on the back wall of the case, but it is more difficult to get there without moving the equipment away from the wall.
If the sticker has worn off or peeled off, try to find a warranty card or receipt, where the full article number is often written down. The data may also be in an electronic receipt or order history if the purchase was made online.
⚠️ Attention: Never try to forcefully tear off a label if it is glued to a plastic panel. The plastic may become deformed or crack, and it will be impossible to restore the factory markings.
It is important to distinguish between model and serial number. A model is a device type (e.g. GA-B489SVQZ) that is the same across thousands of units produced. The serial number is a unique code for a specific instance, which can often be used to calculate the production date.
Labeling logic for Bosch and Siemens refrigerators
German brands Bosch and Siemens use one of the most transparent systems coding, where the production date is encrypted directly in the serial number. This allows you to instantly determine the age of the equipment, which is critical when buying a used device.
The serial number usually consists of 10 characters. The first three digits indicate the manufacturer's code. The fourth digit indicates the year of manufacture, and the fifth and sixth digits indicate the month. For example, if the serial number contains the number 3 after the plant code, then this may mean 2013 or 2023.
The rest of the number is the serial number of the device on the conveyor. Knowing this logic, you can easily determine whether they are selling you a “new” device that has been in the warehouse for five years.
Year correspondence table in Bosch/Siemens serial numbers
Digit 9 = 2009 or 2019; Number 0 = 2010 or 2020; Digit 1 = 2011 or 2021; Digit 2 = 2012 or 2022; Number 3 = 2013 or 2023. The cycle repeats every 10 years, so you need to take into account the approximate age of the equipment visually.
The model range also carries information. The letters at the beginning often indicate the series or type of installation (recessed or freestanding). The numbers after the letters indicate volume and functional features. For example, the presence of a letter K often indicates the presence of a freshness zone.
Deciphering LG and Samsung codes
The Korean giants use more complex alphanumeric combinations. In LG models, the first two letters usually indicate the type of refrigerator (for example, GA - two-chamber, GR - multi-chamber). The numbers that follow them indicate the useful volume in liters.
Followed by letters coding the design, type of control and color. The last letter in the article often means the region of delivery or a specific modification for a certain chain of stores. Understanding this structure helps you find an exact copy of a door or shelf.
Samsung has a similar principle, but has its own nuances. Samsung serial numbers often have the production date encoded in the first characters, but the format may vary depending on the year of manufacture. The format YYMMDD (year, month, day) at the beginning of the line is often used.
It is important to pay attention to regional codes. A model intended for the Asian market may have different electrical parameters or refrigerant than its European counterpart, even if they are visually identical. When ordering electronics, this plays a decisive role.
Features of marking Indesit, Ariston and Candy
Italian brands that are part of the Whirlpool or Haier group use their own system. In Indesit and Ariston articles there is often a color code at the end of the line. For example, the number 00 may mean white, 10 – silver, and 03 – black.
The serial number for these brands contains information about the release date in the form of a code. Typically these are letters and numbers, where the first letter represents the year and the next number or letter represents the month. The encoding of months may be non-linear (for example, 1-9 for January-September and A, B, C for October-December).
To accurately determine the date, it is sometimes necessary to refer to official decoding tables, as they change every few years. However, knowing the approximate year of purchase, you can easily compare the data.
⚠️ Attention: When ordering doors for Indesit or Ariston, be sure to specify the color code, since the shades of “white” or “steel” may differ between generations, and the new door will differ in tone from the old body.
In the Candy model range Often an abbreviation for the type of refrigerant and energy class is used in the model name itself. This allows you to quickly assess the cost-effectiveness of the device without studying the full specification.
Color matching table in the marking
One of the most common reasons for searching for information on a model is the need to replace damaged housing elements. To ensure that the new element does not stand out from the general appearance, you need to know exactly the color code encrypted in the article.
Below is a table with the most common color designations for popular brands. Please note that the same code from different manufacturers may mean different shades.
| Brand | Color code | Color description | Note |
|---|---|---|---|
| LG | S / Silver | Silver / Stainless steel | Often textured |
| Bosch | 00 / White | White | Basic color |
| Samsung | B / Black | Gloss black | Prone to scratches |
| Indesit | 10 | Silver | Metallic |
| Haier | U | Grey titanium | Matte surface |
Use universal codes RAL is rare, mainly in the premium segment or built-in equipment for painting. In the mass market, manufacturers use their own palettes.
How to determine the year of manufacture by serial number
Determining the age of a refrigerator is a key skill when buying second-hand equipment or used spare parts. The service life of the compressor and the condition of the insulation directly depend on the number of years of operation.
As already mentioned, for Bosch and Siemens this is the fourth digit of the serial number. LG often uses the first digit of the year and the letter of the month (A-January, B-February... L-December, skipping some letters). For example, 705... may mean May 2017.
In Samsung's older models (before 2015), the date could be printed separately on a sticker in the format YYYY-MM. In new models it is integrated into the long code serial number. The first two digits are often the year, the next two are the month.
☑️ Checking the age of the refrigerator
If the encoding is not obvious, you can use online dating calculators by entering the first characters of the serial number. This will save time and eliminate errors in calculations.
Why do you need an exact model during repairs
Many owners try to order spare parts, simply calling them “Samsung two-chamber refrigerator.” This is a gross mistake, since even within the same series different compressors, control boards and types of evaporators can be used.
The exact model (Full Model Code) is necessary for selection:
1. Electronics modules (the board can be re-flashed for a specific volume and function).
2. Shapes of evaporators (they may differ in length of tubes and mounting by millimeters).
3. Fans and sensors (different voltage or wire length).
⚠️ Attention: Do not rely solely on the appearance of the part. Two visually identical fans may have different rotation speeds or blade angles, which will lead to noise or overheating.
Use full model code guarantees that you will receive a part that will fall into place without “collective farm” fitting of wires or digestion of tubes. This is especially true for No Frost systems, where the geometry of the air ducts is strictly regulated.
FAQ: Frequently asked questions
What to do if the sticker with the model is completely erased?
If the sticker is unreadable, try to find the purchase documents or the box. If they are not there, you can try to find the remains of the sticker under ultraviolet light (sometimes traces of glue or embossed symbols are more visible). As a last resort, the technician can tell you the exact model when diagnosing the control board, since the firmware often contains a model code.
Is it possible to find out from the model what kind of freon is in the refrigerator?
Yes, often the type of refrigerant (R600a, R134a) is indicated on the same label as the model, usually next to the inscription "Refrigerant". This is rarely encrypted in the model code itself, but by the year of manufacture (which can be found out from the serial number) one can guess the type of gas: in modern models it is almost always isobutane (R600a).
Is the model for Russia and Europe different?
Yes, the last letter or number in the article is often different. This is related to the climate class, compressor voltage and control panel language. When ordering spare parts from Europe, make sure that the electrical part (connectors, voltage) matches your version.
Where can I find instructions if the model is old and out of production?
Instructions are often stored on official websites in archives. Enter the full model code into the search engine with the postscript “manual” or “instructions”. There are also specialized databases of manuals for household appliances, where files are stored for decades.
